Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF9100U is determined by strict equivalence across the following critical parameters:

• Resistance value: 910 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-1TNF9100U meets all electrical and mechanical parameters required for direct substitution. While this part carries a "Not For New Designs" status, it remains electrically and mechanically equivalent and is suitable for replacement applications where the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1TF9100U is the preferred selection for new designs due to its active production status and anti-sulfur feature enhancement. The ERJ-1TNF9100U serves as a direct electrical and mechanical equivalent for replacement or legacy system applications where the primary part is unavailable. Both parts carry identical AEC-Q200 automotive qualification and ROHS3 compliance, ensuring equivalent reliability performance in automotive and industrial environments.

The distinction between these parts is product lifecycle status only; electrical performance and mechanical compatibility are fully equivalent across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF9100U be used as a direct replacement for ERJ-S1TF9100U?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 910 Ohms ±1%, 1W power rating, 2512 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. The primary difference is product lifecycle status.

Q: What is the significance of the "Not For New Designs" status on ERJ-1TNF9100U?

A: This designation indicates the part is in mature or declining production phase. It remains fully functional and compliant with all specifications but should not be selected for new product development. It is suitable for replacement, repair, or legacy system applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical 2512 (6432 Metric) package dimensions: 0.252" L x 0.126" W (6.40mm x 3.20mm) with maximum seated height of 0.028" (0.70mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet automotive reliability standards?

A: Yes. Both ERJ-S1TF9100U and ERJ-1TNF9100U carry AEC-Q200 qualification and ROHS3 compliance, meeting automotive industry reliability and environmental requirements.

Q: What is the difference between anti-sulfur and standard thick film composition?

A: The ERJ-S1TF9100U includes anti-sulfur coating as an additional feature. Both parts are thick film composition with identical electrical performance. The anti-sulfur feature provides enhanced protection in corrosive environments.
